Comment 62 for bug 1641290

@mirek If the device is not recognized, there's nothing libfprint can do. You can maybe try a more recent kernel. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1700657 for a similar bug

@Mustafa You have 0x0903 reader which should work (more or less) but the problem is it doesn't respond to commands at all. Not sure why, maybe try another usb port, if possible.
